MACHINE FOR RULING PAPER.

Specification of Letters Patent No. 6,645, dated August 14, 1849.

To aZZ whom it may concern Be it known that I, WILLIAM S. VILDER, ofBoston, in the county of Suffolk and State of Massachusetts, haveinvented a new and `useful or Improved Machine for Ruling Paper; and Ido hereby declare that the same is fully described and represented inthe following specification and accom# panying drawings, letters, andreferences thereof.

Of the said drawings Figure 1 denotes a top view of my improved machine.Fig. 2 is a front side elevation of it. Fig. 3 is a vertical, cent-ral,and longitudinal section of it. Fig. 4 is a vertical, central, andtransverse section of it, the saine being taken so as to represent theexpansion endless belt and its supporting frame, to be hereinafterdescribed.

The frame work which supports the operative parts of the machine is seenat A, and is constructed in any suitable manner. It sustains two boardsor plat-forms B, and C, which are disposed horizontally and parallel toeach other, and in other respects with regard to one another as seen inFigs. 1 and 3.

An endless band D, runs and rests on the top surface of the t-able orplatform B, and also around two rollers or cylinders E, and F, arrangedwith respect to the platform B as seen in Fig. 3. The said endless beltor apron D, operates in connection witha second endless apron or belt G,which is disposed with regard to the apron D as seen in Fig. 3, and madeto run partially around the roller F, and to encompass the inferior orlower plat-form C, and be supported by and run around three rollers, H,I, K, arranged as seen in Fig. 3. In its passage over the roller E, t-heendless apron Gr, is made to run in contact with that part of the apronD, which extends around the,

roller. A

The roller K, at the front end of the platform C, has a small cylindera, fixed on its shaft; the said cylinder being for the purpose ofenabling the attendant of the machine to rotate the roller K, asrequired, which he can do by applying his hand to the cylinder andrevolving it. In lieu of the said cylinder a simple crank might be used,but on some accounts I prefer the cylinder to the crank.

L, is the main ruling or bed cylinder. It

is placed at one end of the machine and rotated by means of a crank B,aiiiXed to its shaft. The said cylinder has an endless apron R,extending around it, and several guide rollers M, 0, (Z, Fig. 3. Thisapron operates in connection with a series of endless bands or tapes Z),b, b, &c., which are extended around several guide rollers M, N, O, P,Q, disposed with respect to one another, the cylinder L, and the endlessaprons D, and Gr, as seen in Fig. 3. The ink fountain is represented ats, and the series of ruling pens at e, e, e, &c., they being applied tothe main ruling cylinder and made to operate substantially as in otherruling machines of the character of the one herein described.

T, Figs. 3, and 4, is a small stationary roller arranged directly overand parallel to the guide roller c, before mentioned; the said roller T,being supported by a hori Zontal cross bar U, which may be so affixed tothe main frame A, Yas t-o be capable 'of being raised up or lowered downso as to carry the roller T, nearer to or farther from the roller 0, asoccasion may require. An endless belt V, is made to run around theroller T, and two rollers IV, and X, arranged as seen in Figs. 3 and 1.This belt should be made of caoutchouc or some other proper elasticsubstance which will admit of extension and contraction in the directionof its length. The upper roller, viz, the roller X, on which it runs, issupported by a frame Y, which slides between the posts of a gallowsframe Z, erected on the cross bar U, and has a screw j", c, &c., soapplied to it and the frame Z, as to enable a person by turning thescrew to either raise or lower it (the frame Y,) at pleasure. The rollerIV is put in revolution and so as to revolve the elastic endless belt,by means of a crossed endless band g, which runs around it and the mainruling cylinder L.

A projection or prot-uberance 71 is made on the belt V, and operates aswill be hereinafter described. A crossrocker shaft i, has an arm Z1,projecting from it, and supporting a small roller or wheel Z, which isplaced on or directly over the endless apron G, and in the posit-ion asseen in Figs. 1 and 2. The roller is pressed down toward the apron bymeans of a spring m, suitably applied to the cross rocker shaft i, andthe main frame A. In connection with the roller or wheel Z, a smallspring or wire n, is made to project from the arm 70, and to rest on thepaper preceding or below it.

when passing underneath it. Besides the above a small gage or thin pieceof metal o, is made to extend down from the arm 7c, as seen in Fig. 2.At the rear end of the machine or that end of it at which the paper isdischarged after being ruled, an inclined table or board p, is made toextend downward and outward from the roller Q as seen in Fig. 3. A guideledge or strip s, is fastened to, and extends above the upper surface ofthe board or platform B. Another and similar ledge t, is also appliedand fastened to the upper surface of the board o, and so as to bedirectly underneath and parallel with the ledge s; each of said ledgesbeing made to extend from one end of its platform to the other end ofit.

Having thus described the principal operative parts of my machine, Ishall now propeed to explain the manner of ruling paper In the firstplace the sheets of paper to be ruled are spread out on the top surfaceof the endless apron D, and in such manner that while one end of eachsheet shall be pressed close against the guide ledge s, that edge of itwhich is perpendicular thereto, and next adjacent to the cylinder orroller F, shall be a little or a short distance farther back from thesaid roller, than is the corresponding adjacent edge of the next sheetbelow; and so on throughout the pack or collection of sheets. This beingeffected the operative or attendant on the machine applies his hand tothe cylinder a, and turns it in the direction denoted by the arrow inFig. 2. This puts the endless aprons D,y

and G, in motion and causes t-he pile of sheets to pass between the saidtwo endless aprons, and from the upper one down upon the lower one; thesaid sheets in the mean# time being turned over or reversed in suchmanner, that the side of each sheet which was upward when on the belt D,is downward when on the belt Gr. Each sheet on the belt Gr, will besomewhat nearer the eX- pansion belt V, than the sheet immediatelyConsequently when the sheets are advanced toward the place of meeting ofthe projection h, (of the endless expansion belt V,) and the endlessapron R, the upper sheet will be iirst seized by said projection and theapron R, and drawn in between and by them, and off the pile. The

next upper sheet will be next seized and drawn in, and so on through thepile or collection. Each sheet while passing between the projection t,and the apronR, is presented between the series of endless tapes b, b,Z2, and the apron R, and is by the same drawn forward, carried under theruling pens, and ruled by them, while it passes under them. Thence it iscarried downward, and turned over or reversed, and thence movedbockward, and on the tapes and finally discharged over the roller g, anddrops down upon the inclined table or board A29, and is finally arrestedby the upright ledge g, thereof. While each sheet is being drawn off theapron G, the workman advances the next sheet toward the belt V, andstops it when its rear edge reaches the gage 0. As soon as the precedingsheet has been fully drawn ofi the apron G, the second or next sheetwill be seized and drawn off.

The object of making the belt V, an expansion belt, is to enable us toso regulate its length, that is increase or diminish it, that theprojection of it during each revolution may be brought around at theproper period of time, to seize or act on each sheet of paper. As thesheets of different reams vary somewhat in length, the necessity of thisincrease or diminution of the length of the belt, becomes manifest inorder that the machine may be adapted for ruling the various kinds ofpaper found in the market. Besides the above my machine on dischargingthe sheets upon the table 79, restores them all to their originalposition in the pack or quire, which is very important in order to havesameness of appearance of the edges of the pack.

What I claim as my invention is- The expansion belt V, and projection 71in combination with the endless apron R, and the machinery for gagingand delivering the sheets of paper thereto substantially as specied; thesaid machinery being the endless aprons D, and Gr, and gage 0.

In testimony whereof, I have hereto set my signature this 28th day ofFebruary, A. D. 1849.

WILLIAM S. WILDER.
